electrical diagram for radiator front fan

[Viala]

Hello,
yesterday my TS 3800 1992 was heating too much, I looked at the sensor the electrical relay and the fan . When i put an electrical wire in the plug of the sensor to make a contact , the relay makes a clic and stop , if I do the contact again it clicks and stops again but nothing more. Is there another system in the electrical circuit that cuts the relay?

Strange problems that I want to fix as soon as possible , because in Paris the circulation is difficult and the engine heats too much.

Thank you for your help

THis is the diagram www.avigex.ca/xport/fandiagram.jpg
Jiggling with the sensors is no good idea. THis is no switch: it informs the computer of engine temperature and the computer turns the fan relays ON or Off. Feeding 12V to sensor is a no-no; grounding the computer side of the sensor is like a very high temp..may be too high and computer will see an error, possibly explaining what you describe.
Waiting for the real source of the problem, I would instead install a switch to ground the low side of the relay coil: no danger to either computer or relay or sensors.

EH...Paul...I was driving a Renault camping car through Paris in 1993 when the thermostatic fan switch stopped working and the needle started going up in the Montmartre area. Happily, even in vacation, I carry some emergency gear...like a few wires and the like, so I bypassed the switch. THe fan pulled so much current from the alternator that it hampered the acceleration on the open road so I finished the trip through Britany and back to England wiring the fan in and out depending of driving conditions....

hello again

It is difficult for me to understand the diagram

I see many sensors ,relays , coolant pusher? coolant puller? request! input !
and so on......but i cannot see the direct way from the T° sensor to the relay.
P101 is it a caoutchouc made to pass wires in the car?
Are the Coolant pusher/puller fan control in the computer?
Is ECT on the engine
Is the big Fan the pusher or the puller?
Thank you for your help

Les senseurs de température sont "analogiques" et donnent une mesure continue de température au PCM. Ce ne sont pas des switches.
Les ventilateurs sont commandés par le PCM via les relais.
Le PUSHER FAN est celui qui est devant le radiateur
Le PULLER FAN est celui qui est entre le radiateur et le moteur.
P101 est un passage d'une "couette" de fils entre le compartiment moteur et l'intérieur de l'habitable.
and yes the ECTsensor is on the engine, near the thermostat housing...i'll check.
